Temperatures and enthalpies of fusion as well as the heat capacity of silver chloride and silver bromide were measured by differential scanning calorimetry. A polynomial heat capacity dependence on temperature was used to fit the experimental data. The thermodynamic functions of AgCl and AgBr were calculated by combining these heat capacity results with the entropy at 298.15 K, temperatures, and enthalpies of fusion.

Differential scanning calorimetry (DSC) was used to investigate the phase equilibrium in the AgCl- NdCl3 system. This binary mixture represents a typical example of simple eutectic system, with eutectic composition x(AgCl)=0.796 and temperature Teut = 668 K, respectively. The electrical conductivity of AgCl-NdCl3 liquid mixtures, together with that of pure components was measured down to temperatures below solidification. Results obtained are discussed in terms of possible complex formation.
